Paint Job Transforms Walls Into Sensors, Interactive Surfaces

Smart walls react to human touch, sense activity in room

Walls are what they are – big, dull dividers. With a few applications of conductive paint and some electronics, however, walls can become smart infrastructure that sense human touch, and detect things like gestures and when appliances are used.

Researchers at Carnegie Mellon University and Disney Research found that they could transform dumb walls into smart walls at relatively low cost – about $20 per square meter – using simple tools and techniques, such as a paint roller.

These new capabilities might enable users to place or move light switches or other controls anywhere on a wall that’s most convenient, or to control videogames by using gestures. By monitoring activity in the room, this system could adjust light levels when a TV is turned on or alert a user in another location when a laundry machine or electric kettle turns off.

“Walls are usually the largest surface area in a room, yet we don’t make much use of them other than to separate spaces, and perhaps hold up pictures and shelves,” said Chris Harrison, assistant professor in CMU’s Human-Computer Interaction Institute (HCII). “As the internet of things and ubiquitous computing become reality, it is tempting to think that walls can become active parts of our living and work environments.”

Traditional secrets to keeping cool—investigating Okinawan textiles

When Yoko Nomura moved from warm, dry California to the subtropical island of Okinawa, she was struck by the stifling heat and humidity. Searching for ways to survive the Okinawan summer months, Nomura, from the Science and Technology Group at the Okinawa Institute of Science and Technology Graduate University (OIST), discovered a traditional secret to keeping cool: a material called Basho-fu.

Basho-fu is an Okinawan textile fabric made from banana plant fibers. Originating from the 13th or 14th century, Basho-fu was used to make traditional Okinawan kimonos. Basho-fu kimonos were popular among all classes of people in the Ryukyu Kingdom, which ruled Okinawa from 1429 to 1879. Basho-fu textiles were highly durable for hard labor such as farming and fishing, and were comfortable to wear in the hot and humid subtropical climate of Okinawa.

The expertise required to make Basho-fu textiles has been passed down through generations of craftspeople in Okinawa. However, the traditional craft is now under threat from a shortage of banana plant materials and an infiltration of modern methods.

In an effort to rescue and document this important part of Okinawan folk culture, researchers from OIST, in collaboration with the University of the Ryukyus and the Kijoka Basho-fu Association, used scientific techniques to characterize Basho-fu materials and to compare traditional and laboratory Basho-fu production processes.

New 3-D Printer Produces Delicate Soft Objects

A new method of depositing drops of soft materials in a gel could be a new way to print squishy three-dimensional products like living tissue, soft robots and flexible electronics.

In the technique created by University of Florida researchers, a computer-controlled hollow tip precisely embeds fluid droplets of silicone, hydrogel, colloids or living cells inside a granular medium bath the consistency of hand sanitizer. After using the method to make tiny complex soft structures like delicate jellyfish, a tubular knot and a gel version of the nested shapes called Russian dolls, the group says they might have created a new era for engineering.

Apple yanks drone-strike-tracking app from App Store

The app, Metadata+, was created by Josh Begley, research editor for The Intercept; Begley changed its name from Drones+ after it was rejected as “objectionable” by Apple five times.

At the time, an Apple employee told Begley that the app would never be approved if it focused on US drone strikes, but would have a chance if he “broadened his topic” because “there are certain concepts that we decide not to move forward with, and this is one.”

Metadata+ never the word “drone” – this may be how it snuck past the Apple censorship board. But seven months later, Apple has unceremoniously yanked it.

Apple: a giant corporation that gets to decide which journalism you’re allowed to access with apps on your device, and whose lawyersrepeatedly told the US government that changing this situation should be a felony punishable by five years in prison and a $500,000 fine.

Ecosystems work great – they just fail miserably. The important part of a benevolent dictatorship isn’t the “benevolent” – it’s the “dictatorship.”
